Mental Illness And Mental Health - 1724 Words

VISUALISATION Mental illness is one of the major illnesses, some people face in everyday of their life, which can trigger them in one or the other as well prevent them to do things effectively as it use to be. According to Mental Health Foundation (2015), about a quarter of the population will experience some kind of mental health problem in the course of a year, this can happen either by anxiety and depression which is the most common mental disorder in Britain. Women are considered likely to be treated for a mental health problem than men. It is also considered that depression affects 1 in 5 older people (Mental Health Foundation, 2015). Women and Children Health Network (2014) has suggested that about one in five young adults will have depression by the time they are 25. Harris (2008) highlighted that, there is a fact about depression under the ‘’ The British Medical Association Family Doctor Guide to Depression’’. The factual information says every year, doctors di agnose two million new cases in the UK alone about depression, on average, each GP in the UK will have a patient with depression at least in a day and depression can affect any age. This shows a significant of the mental illness (Depression) which can tackle any age group depending on the circumstances. Depression usually starts in the teen years, more commonly before adulthood.

The Same Sex Marriage Debate - 1331 Words

A Paper to End The Same-Sex Marriage Debate The topic of same-sex marriage has been heavily debated for the past decade. Discussions continue whether a marriage is between two people who are in love and agree to spend the rest of their lives together regardless of their sex or if it is reserved for only heterosexuals. Since the beginning of The Gay Rights Movement in the early nineteenth century, groundbreaking developments have come to the surface, presenting strong arguments on both sides of this topic. Currently, there are 1.2 million homosexual people living with a same sex partner in America (Rex). These individuals are not being treated as equals and stripped of their rights because of the person and/or gender they love. Because I believe in equality of all people and that marriage is sacred bond between two people who share an intimate relationship with each other, I believe same-sex marriage should be legal in all states. Same-sex marriage is an important topic to discuss because of the treatment these individuals are receiving. Religious and personal opinions are clouding the judgment of material fact, both of which contribute to this controversial issue. However, there is nothing controversial about equality.

Marketing Plan for the Mongoose Cricket Bat free essay sample

Marketing Plan for Mongoose Style Kashmir Willow Cricket Bat Situation Analysis There is no doubt that Cricket is the most popular sport in India. The cricket bat manufacturing industry in India has been thriving since the time the British first saw the abundance of Willow trees in the Kashmir valley, and introduced the art of bat making in India. The cricket bat industry in India is a 66 crore industry. Bats made of Kashmir willow are second only to the ones made of English willow. These Indian made bats are used by professionals the world over, including star Indian players like Yuvraj Singh and Virendar Sehwag. The raw materials to make bats is plentiful and so is the skilled workmanship required to craft a good quality bat. The cricket bat industry in India is highly unorganized. The most popular brands of cricket bats available in India are BDM, SS, and SG. Recently, there global sports equipment giants like Nike, Adidas and Reebok have also made an entry into this market. The design of the cricket bat has remained largely unchanged since 1771. However, different designs, materials and variations have been tried. The most defining features of a cricket bat are its weight, type of wood and length of the handle. Recently, with the advent of 20-20 cricket and also changes in the traditional 50 over format that encourages batsmen to take more risks, a radical new design in cricket bat has caught the attention of cricket players the world over. It is called the Mongoose bat. As per cricket experts, the mongoose bat with its 33% shorter blade and 43% longer handle will enable the batsman to hit the ball harder and longer by generating higher bat speeds. The physics behind the design are such that the so called â€Å"sweet spot† is distributed throughout the surface of the blade, thus making it an ideal bat for the shorter versions of the game. Opportunity Analysis The advent of 20-20 cricket has revolutionized the game. It has become shorter, faster and more exciting to watch. The mongoose bat could ride on this new wave of change engulfing cricket. Now is the best time to enter the market with a new product. The existing original Mongoose branded bat sells between Rs 17000 and Rs. 23000. Therefore, there is definitely an opportunity to market a similar bat made of Kashmir willow at a much more affordable price for the Indian consumers. Issue Analysis The following are some of the issues that need closer analysis: * The Kashmir bat industry is facing stiff competition from bats made of English willow as the latter is said to be of superior quality * Difficulty in transportation of finished products from the factories in Kashmir is another pressing issue, especially in these days of violent turmoil and political unstability in the valley * A lot of official formalities needs to be addressed and procedures need to be followed to move the finished goods from one state to another. - Another issue is that many of the Indian players were unable to perform satisfactorily by the Mongoose bat in IPL3. This might dissuade Indian consumers from buying the bat. Segmentation Targeting Positioning Our segment is semi professional and professional cricket players. This is because at Rs. 2488, it is priced way over the average price of a regular cricket bat used by amateurs. Amateur cricket players, or recreational players usually play the game u sing a tennis ball and do not require a high grade Kashmir willow cricket bat. The age bracket we are looking at is players around 16 to 40 years old. Kids are not a part of the segment because based on interviews with school coaches and parents, it was observed that kids taking up cricket are encouraged to learn the basics of the sport in the conventional manner. The mongoose bat is a recent innovation in cricket aimed at the shorter versions of the game that encourages hard hitting. Over the years cricket has gotten shorter, faster and more exciting. This product has been positioned to reflect these changes in the game. It has been positioned as a weapon that could give batsmen an advantage in the shorter version of the game, owing to its radical new design. Priced well below the original mongoose bat made in Australia, and at par with conventional bats available in India, it’s hoped that this bat is appealing to players in the new era of 20-20 cricket. Consumer Behaviour When it comes to cricket bats, the Indian consumer is very knowledgeable. We conducted a survey of 40 semi-professional cricket players who have played cricket at a competitive level. 67. % of the respondents were aware of the fact that bats made of Kashmir willow is second only to bats made of English willow. They buy their bats (and other cricket equipment in general) from well known sports shops and can identify the quality of the bat. Celebrity endorsement has little influence on their decision to buy a bat whereas a coach’s recommendation is highly regarded. Based on a survey of sports shop owners, the demand for cricket bats follows a clear seasonal cycle, the summer months and IPL season being the most lucrative for business where they may sell anywhere between 20 to 35 bats a day. Price is an important consideration for the buyers but if the bats are made by the same manufacturers who supply equipment to popular cricket players, then consumers are more likely to buy at a higher price. Competing products/brands The following table lists the major players in the cricket bat industry in India. It includes several well known and trusted local brands that have been manufacturing bats for decades as well as a few international brands that have made a foray into the Indian market recently. It should be noted however, that apart from these brands, there are several local brands available through the unorganized channels, mainly originating at the thriving cricket bat manufacturing industry along the Jammu-Srinagar Highway in Kashmir. Cricket Bats| Brand| Ownership| Geographic Stronghold| Price range of some fast moving brands (in Rs. )| Reebok| Foreign| Mumbai, Chennai| 1500-2500| BDM| Indian| Chennai, Kolkata, Delhi| 1500-2000| SG| Indian| Chennai, Kolkata| 1200-1700| SS| Indian| Chennai, Kolkata| 1000-1500| Kookaburra| Foreign| Mumbai, Delhi| 2000-2500| GM| Foreign| Kolkata| 2200-2800| Bats in the Mongoose style range| Brand| Ownership| Average Price| The Original Mongoose | Foreign| 20000| CW Smasher| Indian| 2500| SAS| Indian| 2500| Analyzing Competition There are currently over 150 different cricket bat brands available in India. This is because the entry barriers in this industry are low. Also, a majority of the brands get their bats manufactured in the unorganized bat making industry of Kashmir where willow is plenty. Bat making is one of Kashmir’s major industries and source of employment. We analyzed the major competitors along the following lines: 1. Market share: The current market share of the major brands like BDM, SS and Reebok in our target segment is close to 80% 2. Brand recall: 75% of the respondents surveyed recalled BDM, SS and SG as the major brands in this industry and associated them with quality and experience in the art of bat making. This poses a considerable challenge to our company in positioning our brand in the minds of the target consumers 3. Share of Heart: 40% of the respondents said that they associate good quality and workmanship with BDM. This shows that the target consumer is very knowledgeable about the nuances of bat making and consider buying cricket bats as buying a work of art. 4. Threat of new entrants: The cricket industry in India is being captured by several well known international sports brands like Nike and Adidas. Reebok has already made an impact and Nike and Adidas are along the same lines, especially after Sachin Tendulkar started using an Adidas bat. With the growing popularity of T-20 cricket and the glamour associated with the sport, the market seems to be ripe for these international brands to make a foray into the cricket equipment industry in India. SWOT analysis of our Company Strength: Highly differentiated product. A radical new design appealing to the youth in terms of its promise to deliver higher performance. High quality workmanship and raw materials used. Weaknesses: The main strength may possibly be a weakness as well. The mongoose design is the first change in the design of a cricket bat since 1771. This shows how traditional the sport is. The new design may take some time to catch on with cricket players, including the youth who may have apprehensions about using a bat with a smaller hitting surface that could possibly increase chances of getting bowled out. Establishing a reliable and robust distribution network as well a sound marketing plan with restricted resources are two of the main challenges. Opportunities: The existing structure of this industry in terms of sourcing raw materials, distribution etc is highly unorganized. This provides us with ample opportunities to merge our company with the existing system. This industry has never indulged in large scale marketing and promotions. This presents us with the opportunity of trying out new promotion plans like tie ups with schools and academies, road shows, setting up stalls at malls, cricket grounds etc. Cricket is booming in the subcontinent as also in Europe. There are plenty of opportunities to expand and get into export of cricket bats in the future. Threats: Several new entrants have made this a rather crowded industry, especially the various international brands. Brands like BDM and SG have always been popular and trusted for their quality. If these brands get into making mongoose style bats, then it poses a severe threat to our company. Raw material prices increasing is another threat. This is owing to the continuing turmoil in Kashmir and government regulations on the felling of Willow trees there. Distribution and Promotion Our survey of sports shop owners revealed that more often than not, there are two levels of distribution in the cricket bat industry. The manufacturer sells to the wholesaler, and the wholesaler to the retailer. The profit margin on an average for retailers was anywhere between 7% to 15%. The margins available to the wholesaler could not be determined as all of the manufacturers contacted refused to divulge such information. Our distribution plan will also involve two levels. This is to ensure smooth supply of our bats into the market and to take advantage of the extensive each and bargaining power of wholesalers. However, in the initial stages, we will restrict distribution only to the medium to big sports shops in the main metro cities of India. This is to gauge the acceptance level of our product and also to keep costs low in the beginning. 5% of the initial investment and revenue generated every year will be used for marketing and promotion activities l ike the following: 1. Slots in the different radio channels during live IPL games. 2. Stalls outside major grounds like the Oval maidan in Mumbai. These stalls would allow the local teams who come to practice there, use our bat on a trial basis and experience its features. 3. Advertisements on banners near cricket grounds, and schools and colleges during the summer months when many youngsters take to cricket coaching. Financial Forecast 1. Preliminary Research Average price of a cricket bat in India – Rs. 1500 Total market for cricket bats in India – 66 crores (Indiamarketsonline. com) Therefore no. of bats sold in a year – 440000 Based on the survey conducted, the average no. of bats owned by the target segment is 2

Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration

Abstract Cardiac arrhythmia is one of the many health conditions that form the basis of aviation medicine. The absence of adequate information around the condition necessitates studies to that effect. The current paper sought to determine the types of cardiac arrhythmia that result from aviation related movement.Advertising We will write a custom research paper sample on Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration specifically for you for only $16.05 $11/page Learn More The study relied on findings made in centrifugal training experiments, where subjects are usually placed in a human centrifuge. The objective was to expose the subjects to +Gz forces, which are similar to the ones in a military jet or a commercial flight. During such exercises, the tolerance level of the subjects was determined relative to the G-forces. It was found that sinus arrhythmia, premature atrial contraction, premature ventricle contraction, and atrial fib rillation are the common cardiac arrhythmias during such exercises. Introduction Aviation Medicine An Overview There are certain health-related problems that are unique to the aeronautical and aviation industry.[1] Rayman points out that aviation medicine can also be referred to as flight or aerospace therapy.[1] The idea behind this kind of healthcare is the need for a medicinal approach in tackling the wellbeing of people in aerospace industries. Pilots and astronauts are good examples of individuals who are covered by aviation medicine. The principle behind this field is the fact that the patients find themselves physiologically affected by aviation-related factors, such as gravity. Advancement in the aerospace and aviation sectors imply that most of the aforementioned factors will increasingly affect the persons in the industry. Hanada, Hisada, and Koichiro affirm that progress is inevitable in the aviation industry.[2] An example is the case of air force pilots. The need to dev elop faster and effective jets means that the aerodynamic factors will be modified. Consequently, the pilots end up being affected by some of these forces. The advancements made in aviation medicine rely on its relevance to the world of aerospace. Whinnery indicates this importance by outlining the fact that the United States Air Force (herein referred to as USAF) has a School of Aerospace Medicine.[3] Such institutions justify the reasoning that research in aviation medicine is important. In a study to determine the state of affairs in Singapore in relation to this field, Gan, Low and Singh focus on the military and commercial flight areas.[4] In these fields, there is constant development of new and state-of-the-art machinery. However, as aforementioned, the same comes with consequences like increased arrhythmia.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Technological innovati ons in medicine are required in such fields as aviation physiology and performance maximization.[4] Other areas in which advancement is required include the selection of medical standards and protection of aircrew from communicable diseases, which may arise during a flight. However, for the purposes of this paper, discussions will revolve around the physiology aspect of aviation medicine. G-Forces in air planes Airplanes are constructed in such a manner that they respond to the laws of aerodynamics.[1] The operation of these laws relies on gravity and how to overcome it. Whinnery brings out the understanding that gravity, as a force, is observed as acceleration.[2] The implication is that there is motion involved. Going by the arguments made in Newton’s laws of motion, it is evident that gravity is characterized by several forces. The study restricts itself to the forces exerted on an aircraft due to gravity, which is referred to as ‘g-force’. According to Gan et al.,[4] g-forces are considered as accelerations, as previously indicated. As a result, one can determine these forces on the basis of their respective weights. By virtue of the acceleration nature of gravity, the g-forces appear to multiply the weights of a given mass. In the context of an airplane, these factors tend to reproduce the weight of the unit mass of the persons in the jet. To appreciate how a pilot will experience this multiplier effect, one ought to obtain the sum of the non-gravitational forces acting on them. The aforementioned non-gravitational forces are considered as the proper accelerations.[1] Their effects include stress and strain on persons in an aircraft. In their study, Whinnery[3] makes the claim that high amounts of g-forces are destructive to the aircraft and to the people. Effects of g-forces on human anatomy G-forces cause strain and stress on the bodies in an aircraft. In line with this, the elements have a physiological effect on human bodies.[1] Ha nada et al.[2] affirm this hypothesis in their study on the effects of g-forces on military pilots. Most of the components of the human anatomy have mass. As such, the effects of stress and strain on them vary. Hanada et al.[2] indicate cerebral perfusion as a major impact of these forces. In such cases, the patients tend to suffer from a condition known as G-induced loss of consciousness (herein referred to as G-LOC). Such conditions are common among military pilots during the maneuvers displayed by the fighter jets. Arrhythmias is another common phenomenon resulting from the g-forces, especially in instances where flight crew are taken through centrifuge training.[4] In such cases, the pilots are subjected to the same conditions as those of a plane in the air. Consequently, the developments tend to alter the rhythmic patterns of an individual’s heartbeat. The effects of g-forces are so serious on the human anatomy to the extent that Hanada et al.[2] propose the presence of specialists during centrifuge training.Advertising We will write a custom research paper sample on Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration specifically for you for only $16.05 $11/page Learn More Effects of G-Forces on the Heart General effects An analysis of g-forces makes it apparent that human anatomy is severely affected by stress and strain, as illustrated in the previous section. Advances in aerospace technology imply that human body will continue to be subjected to such forces to determine its tolerance.[1] For the purposes of this study, it is important to understand the effects of g-forces on the heart as an organ in human anatomy. Cardiac arrhythmia The functioning of the heart is largely attributed to its electrical properties.[1] The stresses and strains brought about by the g-forces tend to affect the organ’s electrical attributes. As a result, the heart beat is altered. Conditions of this nature are what are referred to as cardiac arrhythmia. The condition is not age or gender specific. Whinnery[3] points out that the condition if often not fatal. However, studies illustrate that cardiac arrest is associated with arrhythmia.[2] Cardiac arrhythmia can occur in one of the compartments of the heart.[1] The same explains why there are different types of the said condition. Rayman[1] points out the existence of four types of cardiac arrhythmia. The first is supraventricular arrhythmia, which is characterized by a fast heart rate.[1] Secondly, there is bradyyarrhytmias. The condition arises when the heart beat is extremely low. In such cases, the blood hardly reaches the brain. The third type is ventricular arrhythmias. The occurence is associated with the lower chambers of the heart.[1] Finally, there is premature beats. It is a type of arrhythmia associated with the upper atria of the heart. The ‘premature beats’ are an indication of a mild form of arrhythmia, whose symptom s are not easily noticeable.[5] Cardiac arrhythmia in aviation medicine The aviation industry is a sensitive area, which involves out of space explorations and normal flights. The machines involved are quite complex. The sophistication requires the complete application of the pilot’s cognitive abilities. Within the broad spectrum of aviation medicine, cardiac arrhythmia falls under the physiological effects. The heart plays an important role in human anatomy.[6] As such, studies have been conducted to illustrate how best to overcome the condition. Factors influencing g-force provoked arrhythmia During centrifugal training, the participants are subjected to +Gz forces. The procedure leads to stress that affects human anatomical functions. It is evident that cardiac arrhythmia results from the effects of the G-force on the heart. The rhythms are distorted from their normal patterns.[7] It is important to appreciate the factors that influence the occurrence of arrhythmia due to the G-forces. Over the years, aviation medicine has relied on centrifugal training to obtain information about cardiac arrhythmia. Such information includes the various types of the condition and their influencing factors.[7] Experiments carried out to determine this rely on the use of human centrifuges, which are found in special units. The most common areas where such apparitions are found include special aviation medical departments in military wings.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More One of the factors that influence cardiac arrhythmia during centrifugal training is the magnitude of the +Gz. Ewalina and Lech[7] proved this in a study in which they sought to determine hemodynamic changes resulting from centrifugal acceleration and the corresponding cardiovascular responses. The study reveals that an acceleration of 1Gz is responsible of acute hemodynamic changes. The same magnitude of acceleration was found to be an activator of cardiovascular responses, arrhythmia being one of them.[7] Anti-G straining maneuvers (herein referred to as AGSM) are other factors that influence g-force-provoked arrhythmia. Ewalina and Lech[7] point out that the same has a direct effect on the nervous system, which impacts on the heart’s electrical properties. Such measures are seen as an attempt to reduce the effects of g-forces. They limit the impacts of +Gz on the electrical characteristics of the heart. Other factors include the health status of the subject and the duration of exposure. Latent cardiac medical histories give mixed results. Exposure durations increase the chances of cardiac arrhythmia, which further aggravates the severity of the conditions. Materials and Methods Introduction The current study is hinged on the hypothesis that centrifugal acceleration results in cardiac arrhythmia.[1] The research relies on a series of peer reviewed articles, which provide a detailed discussion of the topic. More importantly, the articles relied on address the issue of g-forces and their effects on human subjects. They illustrate the various types of arrhythmia and their relationship with g-forces. +G Acceleration and Corresponding Detection of Cardiovascular Responses In an experiment, Vettes, Viellefond, and Auffret[6] determined that g-forces have a corresponding cardiovascular response from the heart. The researchers deduced this by carrying out detailed studies on the issue. The subjects used were all male and individually volunteered for the exerci se. The studies were carried out in a laboratory in France. The location, known as the Aerospace Medicine Laboratory of the Flight and Test Center, contained the equipment necessary for this research.[6] The male volunteers had an average age of 37 years.[6] After the preliminary medical check-ups were concluded, all the subjects were found to be medically fit for exposure to g-forces. Preliminary tests carried out at the Central Medical Examination Centre for Flying Personnel, which is situated in Paris.[6] Thirteen of the participants did not have prior exposure to centrifugal acceleration. According to Vettes et al.,[6] +Gz g-forces were required for the study. The said forces are attained when a human centrifuge is rotated longitudinally. The specific centrifuge used in this research had a vertical rotating axis, whose arm was six meters.[6] A gondola is attached at the arm’s extreme end. Human subjects occupy this space. The centrifugal acceleration in this regard is obt ained by means of a perpendicular rotation of the arm relative to the gondola. During this rotation, the apparatus moves along the axis, exposing the subject to the +Gz forces arising from acceleration. To ascertain the responses, certain cardiac parameters are taken into account.[6] Such parameters as the subjects’ rate of heartbeat and arterial pressure were are determined. The study by Vettes et al.[6] required the stoke volume and the subjects’ visual fields to be recorded as part of the preliminary medical analysis. Each of the electrocardiographs was analyzed by means of a special electrode. The electrodes are placed on 3 locations on the subjects’ body. The first two are placed on each of the axillae, while the third is placed on the lumbar spine. In so doing, the researchers minimize the noise that would otherwise be present due to the muscle-related contractions. The arterial pressure on the other hand is obtained by means of a syphgamanomter.[6] The sa id machine is normally inflated by means of an electrovalve that is remotely controlled. To obtain the actual pressure in a subject, a curve on the machine is needed.[6] In addition, there is a microphone placed at a strategic point to detect specific noises. In the study, the researchers were able to record their patients’ rates of heartbeat using a phonocardiograph. However, there are exceptions where the heart rate is determined by taking measurements of 10 systoles from the machine. Safety Criterion The study by Hanada et al.[2] sought to develop a safety criterion for centrifugal training. The study relied on pilots from the Japanese Air Self-Defense forces. Each of the subjects was conversant with F-4, F-15 and F-2 fighter jets.[2] Such familiarity was a requirement to be part of the study. It was meant to ensure that the subjects were all familiar with increased G-forces due to the aircrafts’ high rates of acceleration. As expected, there was a preliminary medic al examination carried out on each of the participants.[7] In addition, the subjects were taken through a pre-determined duration of centrifugal acceleration to obtain specified results. The study created several profiles to analyze the effects of different +Gz forces. The data analysis phase was characterized by anonymity. The names of the pilots were not included in the profiles. G-Force Tolerance In their study, Blue et al.[5] examined levels of tolerance associated with g-forces during centrifugal training. The study revolved around subjects with an interest in spaceflight. The participants were part of Virgin Galactica crew and would- be passengers. An equipment referred to as a ‘Space Training Simulator’ was used in the study. The machine operates like a human centrifuge. Prior to the experiment, a medical examination was carried out. Afterwards, the subjects were taken through an anti-G straining procedure. There was a descriptive representation of the data colle cted in the study. Cardiac Arrhythmias in Flight and Centrifuge Simulations In their article, Ewalina and Lech[7] argue that centrifuge acceleration has an effect on cardiac arrhythmia. Consequently, their study analyzed the two scenarios in which such acceleration is achieved. They examined the rhythm balances when the subjects are in centrifuge training and in actual flight. Ewalina and Lech[7] point out that the two instances have similarities and differences. Ultimately, the research sheds more light on cardiac arrhythmia resulting from centrifugal acceleration. In the study, Ewalina and Lech[7] relied on 20 experienced pilots and 20 students. The student pilots were selected from a group of 3rd and 4th year cadets in the Polish Air Force Officers’ College. According to Ewalina and Lech,[7] the average age of the experienced pilots was 35.3 years. There was an allowance of 4.9 years in the positive and negative extremes. The average height was 176.6 cm, while body mass wa s 79.3kg.[7] The average flying hours of the experienced pilots was estimated at 2620. The trainee pilots, on the other hand, had an average age of 21.9 years and median height of 178.2 cm.[7] Their mean body mass was 78.7kg. They had an average of 252 flight hours on their records.[7] One of the requirements for participation in the experiment was that none of the pilots should take any form of medication. Ethical issues were also taken into consideration, where the participants were required to submit a written consent. The approval to conduct the study was granted by an ethics committee constituted by the ‘Polish Air Forces Institute of Aviation Medicine.’[7] The study required the subjects from the two groups to carry out flight protocols in pairs, where one acted as a pilot, and the other as a passenger.[7] Each of the subjects was required to make 2 flights. In the first flight, the subject was required to act as a ‘pilot’ (herein referred to as AF). The second flight demanded that they act as a passenger (herein referred to as PF). According to Ewalina and Lech,[7] the participants were required to take a break in-between the flight schedules. The study gave an allowance of 1 hour as the duration of time that each pilot should take before taking part in the next flight. To attain consistent results, all the subjects made use of the same TS-11 ISKRA Jet.[7] Once all the pilots had made their required flights, the researchers took a break of two days. During the break, the subjects underwent human centrifuge tests. It is important to note that the subjects did not wear G-suits during the study. The omission was meant to allow the +Gz effects to be conclusively examined. The forces were generated from the maneuvers carried out in the flight program. They ranged from 0.57 G.s-1 to 4Gz when the maneuver involved three successive turns.[7] With regards to the split S maneuver, the acceleration was recorded between 1.7G. s-1 and 5.6 G z.7 The ‘two-successive loop’ maneuver was characterized by an acceleration of 1.4G.s-1 to 5.0Gz. The other maneuvers carried out were the immelman and the one turn. The former had an acceleration of 5.6Gz, while the latter gave results identical to all the other maneuvers.[7] The results from the flight protocols were recorded separately. As aforementioned, the study carried out a centrifuge test. The same was realized using a centrifuge with a radius of 10 meters.[7] The equipment was provided by the Acceleration Tolerance Laboratory, which is situated within the Institute of Aviation Medicine. The latter is a department of the Polish Military. At the resting level, the acceleration was +1.4Gz. Thereafter, it was increased by 1G.s-1 to a maximum of 7Gz. When the human centrifuge was involved, the accelerations were set at levels similar to the aerobatic maneuvers.[7] +GZ and the Electrocardiographic Response Whinnery[3] sought to establish that the g-forces experience d during centrifuge training have an effect on an individual’s electrocardiographic (herein referred to as ECG) response system. The study involved a total of 59 subjects. According to Whinnery,[3] the research relied on the responses of the flight surgeons that developed the acceleration profiles of the subjects. The participants were drawn from the United States Air Force and the United States Navy.[3] The two training profiles developed for the study included the gradual and the rapid onsets. According to Whinnery,[3] observation of the subjects was carried out based on their respective ECG dysrhythmias. The first profile was developed when the participants were allowed to put on a standard anti-g suit. Whinnery[3] points out that the suit was not inflated. There various reasons why inflation was omitted. The major objective was to ensure that the subjects were relaxed and that their loss of peripheral vision was gradual. The maximum limit of +Gz was estimated at +9Gz. It is important to note that the tolerance levels during the centrifuge training were recorded from 2 extremes. There was the relaxed and the straining levels of tolerance.[3] In both cases, the aim was to obtain the proficiency of the anti-g element in the experiment.[3] The researchers analyzed the various symptoms exhibited by the subjects. To achieve this, the results were computed in terms of the average, standard deviation, minimum, and maximum.[3] Whinnery[3] used the ages of the subjects to estimate the results. Of particular interest was the comparison between the ectopy occurrences among the subjects. The incidences were analyzed by means of a correlated proportions test referred to as McNemar.[3] An elaborate outline of the results is discussed in the subsequent sections of this paper. The objective, as already mentioned, is to build on the hypothesis of the current study. The discussions will involve results from studies similar to the ones referred to in this section. Resu lts Introduction to the Results From the materials and methods discussed in the previous sections, it is apparent that there is enough evidence to support the hypothesis made in this paper. The evidence suggests that cardiac arrhythmia is caused by g-forces that result from centrifugal acceleration.[5] The results of previous studies conducted in this field highlight the various types of arrhythmias and the effect of centrifugal acceleration on the rate of heartbeat. In addition, the findings made illustrate the various cardiovascular parameters related to arrhythmia. In line with this, analysis of this condition in relation to centrifuge is outlined in this section. Types of Arrhythmias As aforementioned, there are multiple types of arrhythmias. Each of them has unique characteristics that set it apart from the others.[6] In a study to determine the safety measures needed to be put in place during g-flight training, Hanada et al.[2] found out different types of this condition. The findings are illustrated in Table 2 below: Table 1: Types of cardiac arrhythmia Number of Participants Percentage of Occurrence (%) Type of Arrhythmia 114 58.5 Single PVC 95 48.7 Sinus Arrhythmia 63 32.3 Single PAC 19 9.7 Paired PVC 5 2.6 Ventricular tachycardia 3 1.5 Paroxysmal supraventricular tachycardia 3 1.5 Repeated PAC 1 0.5 Paroxysmal Atrial Fibrillation 1 0.5 Ventricular bigeminy or trigeminy Adapted from: Hanada et al.[2] The study by Hanada et al.[2] reveals 9 types of cardiac arrhythmia associated with centrifuge acceleration. The figures listed in table 1 above were obtained from a research conducted by the Japan Air Self-Defense Force (herein referred to as JASDF). The most common condition recorded during the study was single premature ventricular contraction (herein referred to as PVC) at 58.5 percent. The occurrence of both Paroxysmal Atrial Fibrillation and ventricular bigemny or trigemny was recorded at 0.5% in one of the participants, maki ng it the least common of all. Centrifugal Acceleration and its Effects on the Rate of Heartbeat As previously mentioned, centrifugal acceleration has an effect on human anatomy. The effects of this phenomenon on human body vary between different organs. Studies reveal that centrifugal acceleration gives rise to g-forces. As such, it follows that their effects on the heart touches on its rhythms, leading to cardiac arrhythmia.[7] In their study, Whinnery[3] affirms that g-forces affect an individual’s heart rate. Table 2 below illustrates results of the study by Whinnery.[3] The effects of the forces on the human heart are documented in the table. Table 2: G-force exposure and corresponding heart beat rates Lown grade Ectopy Definition Subjects with highest Lown grade 0 Absence of ventricular premature depolarizations 12 1 5 PVC 31 2 5 PVC 3 3 Multiform PVC 1 4A Paired PVC 8 Source: Whinnery[3] In this research, Whinnery[3] relied on one type of cardiac arrhyt hmia. As illustrated in table 2 above, the study examined the rates of heartbeat in relation to the effects of exposure to +Gz forces. The analysis is based on a Lown grading system. Such a system is used to classify heartbeats with regards to cardiac arrhythmia.[8] Whinnery[3] selected a cluster from the known classifications, as shown in table 2. The experiment analyzed results from a total of 59 participants. It was found that +Gz forces affected an average of 11 subjects. The same is inferred from the data in table 2. Cardiovascular Parameters Studies aimed at examining the effects of centrifugal acceleration rely on specified cardiovascular parameters. Vettes et al.[6] posit that the +Gz forces arising from centrifugal acceleration rely on such factors. They determine such responses as cardiac arrhythmia. The said parameters include an electrogram and the visual field of the subject. In addition, the heart rate and humeral arterial pressure of the participants are factored in t he study. They make up the cardiovascular parameters recorded during such experiments.[6] Vettes et al.[6] point out that increased exposure to g-forces was followed by a corresponding increase in the rate of the individual’s heart beats. The results from their experiments illustrated that peripheral loss of vision among the subjects was an indicator of the effects of the +Gz forces. The latter is regarded as a key symptom indicating the onset of cardiac arrhythmia. The study by Vettes et al.[6] revealed that the highest recorded heart beat per minute was 113, whereas the lowest was 84. In terms of pressure, Vettes et al.[6] illustrated that increased exposure to these forces (up to levels of +3 Gz) resulted in a corresponding rise in arterial pressure. To this effect, blood pressure is treated as an essential parameter in understanding cardiac arrhythmia. The same explains the effects of exposure to g-forces. The scenario is similar to electrocardiographic recordings, which vary depending on the accelerations. In their study, Vettes et al.[6] point out that increased heart pressure was the cause of arrhythmia. The reason is that the pressure led to atrio-ventricular dissociation. Effects of Centrifuge Training on the Heart The major focus of this study is centrifugal acceleration and its effects on human anatomy.[9] Aviation regulations require pilots (and in some cases passengers) to undergo some level of centrifugal training. Such trainings simulate the acceleration likely to be experienced in fast moving aircrafts. An example of such instances involves commercial space-crafts.[5] The high acceleration associated with such crafts requires some training to acquaint the persons with the g-forces. Blue et al.[5] carried out a similar study in which occupants of a spaceflight were subjected to centrifugal-stimulated sub-orbital flight. The objective was to create conditions similar to those in a fast moving aircraft. The participants in the study by Blue et al.[5] were all healthy. The simulation was expected to provide information on how g-forces affect the heart. It was also expected to shed light on the influence of the forces on the occurrence of cardiac arrhythmia. Their study used a total of 81 participants[5]. The research by Blue et al.[5] required healthy individuals. As a result, all the participants were subjected to medical screening.[6] Consequently, the initial number was reduced to 77 subjects. Out of this, 65 were men, while 12 were women. Another batch of 21 participants was subjected to cardiac examinations to check for any latent complications. The medical examinations revealed that 16 had histories of hypertension, while 5 had diabetes. Another 5 had undergone a coronary heart bypass. In addition, 17 participants had a history of hyperlipidemia. Prior to the simulation, there were 2 individuals who were found to have severe cases of peripheral vascular disease. The objective of these tests was to obtain exact re sults from the simulations. The aim was to ensure that the findings made were due to g-forces from centrifugal acceleration and not from latent conditions. The participants with medical histories had little complaints from the centrifugal acceleration in comparison to those without backgrounds of medical conditions. However, both sets of participants complained of nausea. The same is common in cases where subjects are exposed to high centrifugal acceleration. Another effect of this development was greyout. To this end, participants complained of incidences of mild greyout. Interestingly, none of the participants experienced any form of G-LOC. There were, however, incidences where the participants would perform head movements with the sole objective of self-inducing sensations similar to coriolis. Discussion Overview From the various experiments highlighted in the current study, it appears that cardiac arrhythmia is caused by g-forces associated with aerodynamics.[10] The various stu dies made reference to centrifugal acceleration. It is not possible to obtain results from the specific aircrafts that the researchers used to generate centrifugal acceleration. As a result, most studies depend on simulations of conditions found in an aircraft.[11] During such instances, the subjects are rotated at speeds that are almost equivalent to those in an aircraft The objective of such simulations is to expose the subjects to g-forces from acceleration.[12] The specific elements observed are the +Gz forces. The designation ‘z’ implies that on a 3 dimensional plane, the said forces act on the z axis. Their effects on the subject are longitudinal. In addition, they are the most common forces that affect the rhythm of an individual’s heart when in flight.[13] The different levels of exposure to g-forces are a contributing factor to the occurrence of the various types of cardiac arrhythmia. The study by Hanada et al.[2] highlighted three types of arrhythmia c ommon among pilots, especially in military jets. The three were identified as PAC, PVC, and sinus arrhythmias. According to Hanada et al.,[2] the three occurred due to the variant levels of exposure to +Gz. For instance, sinus arrhythmia occurs in instances where subjects are exposed to high g-forces. In such cases, the resulting levels of stress are high. The same has an effect on the heart rate. It distorts the rhythm of these rates once the subject comes to rest. It is noted that PVC and PAC are the most common types of arrhythmia that result from interactions with high-G training.[14] Hanada et al.[2] addressed this issue by pointing out that the two are common in normal day-to-day exercises. The researchers found it prudent to do away with centrifuge in cases where subjects exhibited PAC and PVC.[2] The argument is strengthened by the assumption that the two arrhythmias are a normal occurrence among subjects. The study by Hanada et al.[2] introduced the element of grading the r ate of heartbeat rhythms among subjects. The system is essential in determining the degree or severity with which arrhythmia exhibits itself.[15] In this grading system, arrhythmias that are recorded at a grade of three or higher are regarded as severe. It is noted that 10% of the subjects in the study by Hanada et al.[2] exhibited a paired condition of PVC. The researchers argue that the condition is a direct physiological response to the stress experienced during the centrifugal acceleration in training sessions. The Lown grading system for ectopy was developed against the backdrop of the need to characterize the different types of arrhythmia. The same explains why, in the study by Hanada et al.[2], PAC and PVC are graded according to the degree of exposure to +Gz. An example is in the case where there is paired PVC and PAC, while at the same time single cases of PAC and PVC are noted. In both cases, the Lown format becomes vital in highlighting the severity of the different types of arrhythmia. The Lown system is one of the advancements made in aviation medicine. It is used to determine the types of arrhythmias that are permissible in centrifugal training. An example is evident in the study by Hanada et al.[2], where the system is used to sanction centrifugal training in cases where subjects exhibit paired PVC. However, training sessions are terminated in cases where the arrhythmias go beyond a specific threshold.[2] In such cases, the severity of the condition is determined by such factors as proaxysmal atrial fibrillation. Hanada et al.[2] posit that there are certain tachycardiac arrhythmias that reduce tolerance to G-stress resulting from centrifugal acceleration. In such cases, the subjects exhibit PSVT and VT. Their study revealed that PVST is possibly a major cause of loss of consciousness during centrifugal training.[15] The findings made in the current study are best understood from the perspective of a detailed discussion of centrifugal accelerati on and its effects on the heart. In so doing, the researcher aims to prove that cardiac arrhythmia is a result of centrifugal acceleration. In this section, the specific types of this condition are analyzed in detail. Protocols for Centrifugal Acceleration The findings in this study reveal that centrifugal acceleration is an important component of aviation medicine.[16] The process creates an environment that is similar to that experienced in fast moving aircrafts like fighter jets. Such individuals as military pilots and astronauts are the most affected by the G-forces arising from the acceleration of high speed aircrafts. It follows that such individuals require some form of training to acquaint themselves with the strenuous conditions and to help them bear with the stresses brought about by the forces. Centrifugal training, as already indicated, is the process through which pilots and other crew members are subjected to controlled conditions of G-stress. During such sessions, avi ation medical personnel examine individual subjects’ tolerance to G-forces.[2] It is important to take the subjects through certain protocols. Such a move is necessary as it helps in the attainment of accurate results from the exposure to the said forces. Several studies are used to elaborate the importance of these protocols as indicated in the ‘methods’ section of this paper. The first and most important protocol to follow in centrifugal training is preliminary medical check-ups.[1] The procedure is evident in the studies by Hanada et al.[2] and Whinnery[3], where the subjects are screened for heart related complications. The objective of such preliminary medical examinations is to ensure the effects of G-stress exposure are not confused with the symptoms of latent medical conditions. The second protocol during centrifugal studies is the exposure levels.[3] During the training exercises, the subjects must be exposed to varying levels of +Gz so that a proper com parison can be arrived at. For instance, Whinnery and Hickman[8] sought to study mitrial prolapsed and thus relied on centrifugal acceleration. Their subjects were exposed to stress levels of 1G.15s-1 which were gradually increased. There was also another exposure referred to as the rapid onset exposure in which the subjects experienced g-forces of 1 G.s-1. The initial tolerance level is essential in evaluating cardiovascular reflexes.[8] On the other hand the second tolerance level are useful in determining the subjects’ tolerance in terms of the hydraulics. During these exposure levels, in centrifugal training, it is expected that the subjects end up experiencing total loss of their peripheral sight. The aforementioned protocols are key in ensuring that the results are obtained as expected.[8] Arrhythmia Resulting from Centrifugal Training Overview From the findings in this paper, it is apparent that the rhythm of the heart is distorted by the G-stresses during centrifugal training.[17] As previously mentioned, centrifugal training involves rotation of subjects in a contraption referred to as a human centrifuge. The objective is to expose the participants in such exercises to +Gz forces.[3] Consequently, the individuals in such studies are observed to determine how the G-forces affect their human anatomy, of which the heart is a vital component. The contents of the articles referred to in the current paper reveal that there are 4 major types of arrhythmias that result from centrifugal acceleration.[4] The four include sinus arrhythmia, premature arterial contraction, arterial fibrillation, and premature ventricular contraction.[3] In order to categorize each of the mentioned arrhythmias, the author of the current study made observations depending on the levels of +Gz exposure. A detailed discussion is provided in this section. Sinus arrhythmia According to Rayman,[1] the heart has a specific rhythm to which it beats. Consequently, any external force l ike g-stress tends to distort the normal pattern of this organ, resulting in what is now known as cardiac arrhythmia. From the articles reviewed in this study, subjects in centrifugal training experiments were found to exhibit sinus arrhythmia among other complications known in aviation medicine.[9] The study by Hanada et al.[2] revealed that this complication is common during centrifugal training, where the subject’s heart rate normalizes immediately after a rapid heart-beat rhythm. Interestingly, there were subjects who exhibited this particular kind of arrhythmia prior to centrifuge acceleration and the subsequent exposure to the +Gz forces. As illustrated in table 2, the occurrence of the SA in the participants was recorded at 48%. It is important to appreciate that the high occurrence rate is not really due to the centrifugal acceleration. Hanada et al.[2] argue that the condition is a normal occurrence, especially among persons involved in physical training. Studies ill ustrate that the normal rate of a healthy adult lies between 60 to 100 beats every minute.[1] However, some studies indicate that the pattern varies between the genders. A normal female’s heart rate, for instance, is estimated to fall between 47 and 103 beats for every minute.[17] In men, the estimated rhythm is placed at the range of 43 to 102 beats per minute. Alterations in heart beat rhythm due to sinus arrhythmia are not fatal. There are cases where the condition cannot be detected. As such, members of a flying crew who are found to have the condition are not in danger. Premature arterial contraction (PAC) The human heart is fitted with a pace maker that has electrical characteristics.[1] as a result, when this part is exposed to external forces, there are distortions in its normal functioning. Centrifugal acceleration, as aforementioned, has an effect on the organ. The resultant +Gz forces give rise to G-stress. As mentioned earlier, these stressors tend to affect the n ormal workings of the human anatomy. The pacemaker is among the body parts affected. As a cardiac arrhythmia, premature arterial contraction is a phenomenon where the heart’s pacemaker emits signals before the ‘stipulated’ time.[18] The maker is located above the ventricles, meaning that these chambers respond to the distorted signals. As a result, the heart’s rhythm is altered by the ventricle’s ‘irregular’ response. An arrhythmia of this kind is usually common when an individual is stimulated either through exercises or as a result of such beverages as coffee. However, the same is also true when an individual undergoes centrifugal training.[2] In the study by Hanada et al.,[2] PAC exhibited itself in a number of the subjects used in the experiments. Despite the fact that the condition is not lethal, it can present itself in a manner that would require a discontinuation of the training. In such cases, it is considered as clinically sev ere. Hanada et al.[2] point out that repeated PAC is quite severe and advices intermittent discontinuation of centrifugal training among subjects who exhibit the condition. Premature ventricular contraction (PVC) The heart’s functions rely on the electrical impulses of the pacemaker.[19] In cases where +Gz forces are introduced into the human anatomy, the said impulses are interfered with. When such interferences occur, the functioning of some of the compartments of the heart is impeded, resulting in a distorted rhythm of heart beat. As an example of cardiac arrhythmia, PVC is characterized by the contraction of the heart’s ventricles before the expected electrical signal. The name ‘premature’ is sourced from this irregular contraction of the ventricles. The diagram below is an ECG representation of this condition: Graph 1: Premature ventricular beats Source: Vettes et al.[6] The study by Hanada et al.[2] points out that PVC can exhibit itself in differen t degrees. There is the occasional premature ventricular contraction, which is a mild version of the condition. Subjects who present the said condition are allowed to continue with centrifugal training owing to the fact that it is not harmful. The harmful case of PVC involves repeated PVC and Bigeminy, Trigeiny PVC. However, in spite of the fact that it is more harmful in comparison to occasional PVC, the latter case calls for the termination of centrifugal training after some time. A look at the study by Hanada et al.[2] reveals that 19 pilots exhibited the paired PVC condition. The number of subjects who presented the condition in subsequent training sessions kept on decreasing. The same indicates that despite being a common occurrence due to centrifugal training, PVC is only severe when a subject is exposed to High G-Stress over a long period of time without a break. A case in point is a pilot who travels in an aircraft at speeds that result in a stress of 5Gz.s-1 without taking a break. Such an individual is likely to experience a severe case of PVC, which might lead to cardiac arrest.[18] Artrial fibrillation Exposure to +Gz requires some form of tolerance from the persons participating in the centrifugal acceleration exercises.[19] Increased exposure and the resultant stresses affect the heart’s electrical functions. The atrial happens to be another region of the heart that is affected by the G-forces. According to Rayman,[1] the +Gz forces can increase the rate at which the pacemaker emits electrical impulses. When this happens, the ventricles contract in an irregular and erratic manner, leading to arterial fibrillation.[20] Whinnery[3] points out that exposure to G stress in such centrifugal exercises is characterized by atrial ectopy. As is the case with the other arrhythmias mentioned in this paper, this condition can be mild or severe depending on levels of exposure. For instance, Vettes et al.[6] suggest that the complication is regarded as normal when subjects are exposed to +2G for about five minutes. However, the researchers point out that the condition becomes severe in cases where the G-force is increased to +5G and the subjects exposed to the same for a period of more than five minute. Conclusion Vettes et al.[6] point out that centrifugal training, and by extension centrifugal acceleration, has a direct impact on cardiac arrhythmia. In the context of this study, centrifugal acceleration is regarded as an avenue of generating G-forces to create stress on human anatomy. Aviation medicine makes use of centrifugal training to effectively understand cardiac arrhythmia. In essence, this condition is caused by the distortion of the normal heart beat. Whinnery[3] introduced the element of human centrifuge in their study. The contraption is used in aviation medicine to conduct experiments on centrifugal acceleration. During such experiments, two main factors determine how G-forces give rise to cardiac arrhythmia. The two include the degree of +Gz and the duration of exposure. Intensity and duration are crucial elements in explaining the various types of arrhythmias. Hanada et al.[2] point out that centrifugal acceleration in centrifugal training exercises gives rise to 3 main types of arrhythmias. The analysis points out that sinus arrhythmia, premature atrial contraction, and premature ventricular contraction are the most common conditions. Atrial fibrillation is another type of arrhythmia associated with the exercises. Each of the conditions above is graded on their severity depending on the magnitude of +Gz. in addition, the duration in which the participants are exposed to the forces adds to the severity of the conditions. As such, it is important to pay attention to the degree of these conditions among individuals taking part in centrifugal training. The aim is to avert cases of cardiac arrest. Such occurrences are fatal, especially when the subjects are exposed to real time flight conditions. References Rayman BR. Clinical aviation medicine.

The role of women in society is very different today compared to the role of women in Victorian society, in the 19th Century. Discuss this statement with reference to Maggie Tulliver in ‘Mill On The Floss’ Since the book ‘Mill on The Floss’ was written nearly two hundred years ago, it is no surprise that society has changed, especially for women. The fact that Mary Anne Evans had to use a pen name of ‘George Eliot’ as she was a woman and her works would not have been published otherwise, shows alone what the attitudes towards women were, that of sheer insignificance in the country and in the social circle.

Fire Tornado Project

Fire Tornado Project A fire tornado forms when fire is caught up in a vortex. Fire tornadoes or fire devils occur naturally in some wildfires, but you can make a small scale fire tornado yourself. Heres how: Fire Tornado Materials In order to produce a fire tornado, youll need a source of fire and the ability to create an air vortex or whirlwind. The fire tornado is made by placing a container of fire onto a spinning surface. A cylinder of mesh or screening forces the air into a column to force air into a vortex. lazy susan or table or chair that can rotate freelycontainer of fire (e.g., fireproof bowl containing pieces of sponge sprinkled with lighter fluid or alcohol)cylinder of wire mesh or screen with diameter to fit outside the fire bowl. Make the mesh cylinder by rolling a sheet of metal window screening or chicken wire into a tube. Be sure the tube is wide enough to fit around the container youll be using for fire. Staple the ends of the tube to secure it into a cylindrical shape. Create the Fire Tornado Practice this set-up without igniting the fire to be sure your container wont go spinning off. Its a good idea to secure the bowl and screen tube to the lazy susan with tape or glue so that it wont go flying off when you spin the fire. Its also a good idea to have a fire extinguisher handy, just in case. Set the fireproof bowl in the center of the lazy susan. Secure the bottom so the bowl will remain stable when spun.Place the sponge with lighter fluid into the bowl.Set the metal mesh cylinder around the bowl. See if you can spin the lazy susan without incident. You may need to secure the cylinder.Once you are confident of your set-up, ignite the fire in the bowl and slowly start spinning the lazy susan.

Coexistence of six sigma and lean sigma Essay Example | Topics and Well Written Essays - 750 words

Coexistence of six sigma and lean sigma - Essay Example This discussion paper will tackle the viability of both methods to coexist within the company and determine as well the elements and issues that might arise that may result to a conflict between Six Sigma and Lean Sigma. In the course on the discussion I have learned that Service-Quality Management plays an important role in the success of a company. It has been observed that companies share common practices such as strategic concept, Top-management commitment, high standards, and self-service technologies (SSTs). Among these services, the High Standards for services and products is the practice which can be closely associated with the Six Sigma and Lean Sigma methods since its primary and ultimate goal is to provide the consumers with a 100% defect-free service. The former accuracy standard of 98% sounded impressive though when considering companies that operates in very large volumes of products and service, the said percentage will translate to a level that can still affect whethe r the company services will be seen by customers as merely good or if it is a breakthrough service (Kotler and Keller, 2009). In addition, Six Sigma and Lean Sigma can also be applied to further develop a better and faster delivery system. This includes three levels of differentiation – reliability, resilience, and innovativeness. ... ding the consumers with access to better information systems, introduce bar coding and mixed pallets, and provide other systems that would help the consumers. These systems include a customer interface system that would result to an optimal efficiency and effectiveness (Kotler and Keller, 2009). Six Sigma and Lean Sigma will be an indispensible method to deduce the problems that is encountered by the company and help develop a more efficient and effective operations. Quality improvement can increase the profits of a business by reducing rework and scrap, thus creating a smooth production flow. While some companies are faced with the dilemma on choosing which ideology is perfect for process improvement, some companies are utilizing both Lean and Six Sigma. Six Sigma programs are focused and effective but it often takes months to finish. It also creates elite Black Belts who are often disconnected from the department or workplace. On the hand, Lean initiatives are great for boosting pr oductivity, changing cultures, and cleaning up practices. The companies that find the combination of lean/kaizen and Six Sigma methods as the most effective way to eliminate flaws have been successful in improving their production and continually improving the processes within the business (Smith, 2003). Alternative process design and improvement strategies can be deduced using a decision flowchart. If the process is fundamentally flawed or new it will require a Business Process Design or a Design for Six Sigma. If the process is not that flawed or it is an existing process, the nature of the problem will have to be determined whether it has too much variation or if it has too much waste. Too much variation in the process will require the DMAIC approach of the Six Sigma while too much waste

THE EVOLUTION OF AMERICAN FOREGIN POLICY SINCE THE AMERICAN REVOLUTION Essay

THE EVOLUTION OF AMERICAN FOREGIN POLICY SINCE THE AMERICAN REVOLUTION - Essay Example After a brief but important war with Spain in 1898, the United States became, almost at once, a world power with distant colonial possessions. While some Americans believed that their national identity suited them for such overseas expansion, others questioned it. In addition, reformers began to demand greater involvement on the part of government in solving the problems of the poor and the helpless and of protecting the nation’s natural resources. Several factors contributed to the new idea of overseas expansion. New railroad lines and government land policies brought a flood of settlers to the American West. The desirable land there was quickly settled. When the Bureau of Census officially announced the end of the frontier in 1890, some Americans began to fear that the nation’s opportunities for growth would end. Another factor in the growing interest in expansion was American nation’s rapidly increasing production of goods. By the late 1800s American farms and factories turned out increasing amounts of crops and manufactured goods. American began to seek out new markets for those goods that could not be sold at home. Foreign markets for these surplus goods were considered essential for the nation’s continued economic growth. (Hall, 1999) In the late 1800s a new spirit of imperialism, the policy of extending one country’s rule over other nations and colonies, developed in Europe. Great Britain, France and Germany colonized Africa and turned eagerly toward Asia. Some Americans shared this spirit. Some believed that American empire would help less fortunate people all around the world. These Americans believed that the cultures of Asia, Africa, and Latin America were inferior to American and European cultures. They believed Americans had a duty to civilize these people by showing them American ways of governing and working. American missionaries also

Middle Ages vs Renaissance Art Periods Essay Example for Free

Middle Ages vs Renaissance Art Periods Essay When seeking two art periods to compare and contrast, fewer artistic examples provide a starker depiction of radically changing ideas and mentality than the art of the Middle Ages against that of art from the Renaissance. First, art originating from the Middle Age will be thoroughly analyzed for context. Afterward, art from the Renaissance period art will be analyzed next to it for its departures on from Middle Age techniques and thinking, before the two are finally systematically compared and contrasted. First, art from the Middle Ages, also called art from the Medieval period, characterized a European period of little social change, general poverty, and few scientific advances. The Catholic Church remained an imposing force upon Midieval society, and dominated much of daily life. Art clearly served the role of worship above all else, and the Catholic Church actually commissioned much of the artwork of the period. Much of this art filled churches and monasteries, and took the form of sculptures, paintings and drawings, stained-glass windows, metalwork and mosaics, among other forms. The iconographical nature of the art is substantial, as it above all served the purpose of perpetuating the Catholicism of the early church. It was largely confined to Europe and areas that the Byzantine and Roman empires had once occupied, such as parts of northern Africa. It lasted almost a thousand years, from approximately around 500 C.E. to perhaps as late as 1400 C.E. The depictions within the art reflected its purpose – worship. Religious icons such as saints, the Virgin Mary, Jesus and his disciples, and other depictions provided clarity and images for believers. The images portrayed onto the media arguably reflect the times, lacking in brightness, movement, or attitude. The characters shown rarely appear upbeat. An excellent example that validates some of these generalities is Pietro Cavallini’s The Last Judgment. This painting in the Santa Cecilia in Rome uses drab colours to show what appears to be an angry Jesus overlooked by six angels, three on each side. While a beautiful work of art no doubt, the painting has little passion or movement and does not inspire anything more than fear from a fiery God. This Medieval Art from the Middle Ages contrasts sharply with the Renaissance-era works in many key ways. First, Renaissance Art, while not entirely secular to be sure, had certain overtones of the humanism sweeping Europe. Next, its style exuberates brightness, passion, and an appetite for life that cannot be found easily in Middle Age art. Renaissance Art effectively superseded and ended art period progressing during the Middle Ages, and this mirrored social trends of increasing wealth and prosperity, upward mobility, and technological advances of the time. While no doubt heavily influenced by the preceding art of the Middle Ages and often building off of some of its topic such as Christianity, Renaissance Art has a strong hint of humanism which afflicted its artists. This philosophy sought to change the nature of man’s relationship with God to exist outside the church’s realm, and the â€Å"Renaissance men† often meaning that these artists were not only artists but commonly philosophers and scientists as well. Michelangelo, who was a painter, architect, poet, engineer, and sculptor, exemplified these characteristics. His masterpiece in the Sistine Chapel, The Last Judgment, provides us a great comparison to Cavallini’s work on the same topic and contrasts the vastly different techniques and focuses of the two art periods. While Cavallini’s work lacks a variety of colours and could be described even as plain, Michelangelo’s work gives a clear view into his mind’s eye, filled with numerous angels and men moving through the heavens. While Jesus is still at the top and the Madonna next to him seems to cower in fear at his wrath, many nonetheless are lifted upward. The bright colours, quick movements, and in fact original nakedness of the characters (later covered up, at the church’s request) reflect the technique and thought process of Renaissance-era art. So taking the topic of the Last Judgment, the second coming of Christ as a comparison subject matter for extrapolation between Medieval and Renaissance art periods, the Renaissance’s brightness, liveliness and energy shine clearly. First, we saw that Middle Age art was dreary, using drab colours and little dynamism that reflected the harsh realities of life in Europe at the time. Second, Renaissance Art ended this period with the new opportunities and advances made during the Renaissance, reflected in art from the period. Multitalented Renaissance men of the period such as Michelangelo contributed simultaneously to multiple artistic fields at once. Their art reflected the optimism of the times, the great advances being made philosophically and technologically, and their work captured their excitement for mankind’s newfound humanist relationship with God. What was once seen as an angry God hell-bent on punishment was now an opportunity for a chance into the heavens, and often Renaissance Art was even entirely secular, such as masterpieces like the Mona Lisa. Therefore, the Renaissance period of art departed from the Middle Ages period of Medieval Art not simply in technique or media, but also in subject matter, philosophy, and use. The art periods correspondingly reflected their equivalent time frame as either bleak and dowdy or upbeat and energetic. References Finnan, V. (2013). The last judgement.

Education reform Essay

MSU essay choice #2: Describe a significant experience from the past two years which required you to interact with someone outside of your own social or cultural group (ethnic, religious, geographic, socioeconomic, etc. ). How did this impact you? What did you learn and what surprised you? During my junior year of high school, I went on a mission trip/volleyball expedition with my club team. We traveled down to Nicaragua because this was a new experience for everyone involved. When we first got off the plane it was a completely different atmosphere than what any of us were used to. As soon as you leave baggage claim, you are greeted by a large sea of people. The only thing keeping the two of you apart is a tiny glass door which leads to the streets you exit from. After we left the airport and checked into our hotels we were on the road to do our first part of community service. We met in this large dusty field with make shift bases and a small pitcher’s mound. We later found out that it was home to a youth girl’s kickball league. The girls were from the ages of eight through sixteen. You could tell that they didn’t have much and kickball was there whole life, but they always had a smile on their face and made the best of everything. When we were playing with the girls, we got to talk with them a little bit but there were some barriers because they couldn’t speak English, and we didn’t know much Spanish. Despite that, we were able to laugh and joke with the girls. Seeing the way they smiled and how they were able to make the best or most out of everything showed me that you don’t always need the material things in life that you can be alright and still find happiness. On our next mission trip, we were split into groups to do different assignments. My group was assigned to an elementary school out in the countryside to work with preschoolers. The drive out was very far from town and the smell of animal waste and disease burned your nose. When you finally arrived to the school, it was the size of a traditional school house from early pioneer days. When we walked inside, we learned that it wasn’t only a school for preschoolers, but it was also class rooms full of kids from first to sixth grade. Each classroom was divided by age to try and keep kids learning as much as possible. When we took the children out to play, they looked surprised yet fortunate. I had never seen such a bright smile on a person’s face till I got to play with those kids. When the play time was over and we went to donate the school supplies we brought down for them, they gave us big hugs and much gratitude. At first I didn’t realize why someone would be thanking me for an eraser and five pencils, but then I later realized that theses were all of the school supplies that child would have for the rest of the year or even the rest of their school career. When it came time to leave, not only were we sad, but so were the kids. Later on through the day, we found out that since that school was so far from the main town we were staying in, they never had any visitors and they hardly ever get donations. The school only went up to grade six because by that age, kids could either continue to go to high school, or start working. Hearing all of that made me realize just how blessed I am to live in the country and have the opportunities that I do. Those children may have no say in whether or not they can finish up schooling and go to college to live successful lives. Not every person in life has the choice to better themselves or to change their social status in life.
